The US dollar edged lower against a basket of major currencies on Tuesday on nervousness ahead of US President-elect Donald Trump's first news conference set for Wednesday, while the Mexican peso hit a record low. Investors fretted that Trump, who takes office on January 20, could shake markets at the news conference by taking an aggressive line on issues such as trade policy and relations with China.
The dollar index, which measures the greenback against a basket of six major currencies, has climbed 4 percent since Trump's election on November 8 as investors have bet his promised program of fiscal expansion will boost inflation and growth, leading to a faster pace of interest rate rises from the Federal Reserve.
Speculators had boosted net long bets on the dollar for a third straight week in the week ended January 3, data from the Commodity Futures Trading Commission and calculations by Reuters showed on Friday. Uncertainty ahead of Trump's comments, however, dampened demand for the dollar. Analysts also said traders were watching hearings for the Republican president-elect's choices for senior administration posts, which started on Tuesday with US Senator Jeff Sessions, picked for attorney general. "We're in a political event risk this week," said Mazen Issa, senior currency strategist at TD Securities in New York. "Markets pretty much are in a holding pattern right now."
The dollar index was last down 0.18 percent at 101.750. The index hit a 14-year high on January 3 of 103.820. The greenback fell as much as 0.7 percent against the yen to 115.21 yen, near Friday's more than three-week low of 115.04 yen. The euro, which hit an 11-day high of $1.0626 in early trading, was last up 0.15 percent at $1.0588. The Mexican peso hit a new record low against the dollar of 21.6250 pesos as traders avoided exposure to the currency ahead of Trump's news conference. The peso has fallen on worries over the prospect of Trump's protectionist policies. Sterling steadied after hitting $1.2107 in early trading, its lowest level since October 25, and was last up slightly at $1.2166.
